Microsoft to release Windows 8 test on ARM

According to Bloomberg, Microsoft have announced that they will be releasing a public test version of Windows 8 for ARM devices on Feb. 29 at a mobile conference in Barcelona. However, the Windows 8 on ARM software will only be distributed on test machines with an ARM processor, as opposed to being released as stand-alone software.
It looks like Microsoft are now going the way of Apple, by developing their mobile software as a tightly-controlled ecosystem, as opposed to making Windows available to all ARM-based mobile phones. In a way this would make sense, as replicating their model for PC's onto mobile platforms might be both too difficult technically as well as simply too expensive. My take on it: Microsoft are really trying to preempt Mac OS X on ARM.
